When I was an undergraduate taking a class in thermodynamics several of us discussing things over adult beverages wondered how cold it really would have to be for urine to freeze before hitting the ground? Our theoretical discussions didn't get beyond the second round of beverages, but the poor residents of this town may have a good idea.
My family (Dad's side) is from Nipigon, Ontario, northeast of Thunder Bay - northern tip of Lake Superior. That question has been answered experimentally - yes it does freeze before hitting the ground. I went visitng family in christmas of 1991 with a similar cold snap. Nobody cared up there. It was cold, but it was no excuse. Salt wouldn't melt ice. Computer chips in cars all cracked from the cold. I rented a New Yorker and the climate control died it was so cold. Cousin in law worked maintenance for the local ski lodge. Had to fix, with his bare hand, chair lifts in that cold weather. Humans, with adequate clothing can live and function in such a climate. It also explains all the heavy drinking and reproductive activities - to cold to have fun any other way.
When it got to -60 in Tower a guy from our part of the state made the national news by driving nails with a frozen banana. Was rather remarkable, if sad.
We only had -38 this morning. We're slackers.
